Abstract

The invention improves the accuracy of the adjustment. Float 1 with shank 2 is located in the crankcase, while the float of the hinge is connected to one end of the rod 9, the other end of which is rigidly connected to the piston 8. The piston with the rod is placed in the inner cylindrical cavity 7 of the housing 3, in which The sleeve 11 with the seat 12, which cooperates with the locking element 10 of the rod 9 at the upper piston position, and there is a gap between the stem and the sleeve 11. The oil is supplied from the filling tank through channel A, filled in the overpiston cavity, oil is supplied from the engine lubrication system through channel 5, filled into the piston cavity above the lower end of the piston. in its upper position, and the oil supply to the crankcase through channel 6, made in the zone of the side surface of the piston at its upper position. The time for which the float reaches the oil level in the crankcase depends on the gap between the rod 9 and the sleeve 11 and is adjusted by changing this gap. 1 il. 1C (L

The invention relates to an engine structure, namely to a lubrication system for an internal combustion engine.

The purpose of the invention is to improve the accuracy of adjusting the oil level in the crankcase of an internal combustion engine.

The drawing shows the proposed device

The device contains an oil tank (not shown), a float 1 with a shank 2, a housing 3 with a channel h for supplying oil from a tank, a channel 5 for supplying oil from a twin lubrication system, a channel 6 for supplying oil to the crankcase and an internal cylindrical a cavity 7 in which a piston 8 is placed, a rod 9 with an overrun element 10 and a guide sleeve P with a seat (m 12.

The device works in the following way.

When the engine is operating, the oil under pressure from the engine lubrication system enters through channel 5 into the sub-piston section of cavity 7, keeping piston 8 in the upper position. In this case, the locking element 0 is pressed against the seat 12 of the guide bush P, which prevents the oil from flowing from the cavity 7 into the crankcase. The oil from the filling tank also does not enter the crankcase, since the side of the piston 8 closes channel 6.

Immediately after stopping the engine, the pressure in the cavity 7 under the piston 8 drops and it, together with the float I, starts to drop down. At the same time, the element 10 departs from the saddle 12 and the oil from the piston cavity begins to flow into the crankcase. At the same time (due to the fact that the channel 5 is located above the lower end of the piston 8), the oil outflow rate and, consequently, the time during which the float reaches the oil level in the crankcase depends on the clearance between the rod 9 and the guide sleeve 11.

 By changing this gap, the timing is adjusted so that all the oil in the channels and units of the engine has time to flow into the crankcase until the float is lowered to the steady oil level. If this level is below the permissible, then the piston 8 otkryt channel 6. and the oil from the filling tank through channels 4 and 6 enters the crankcase until the float 1 and piston 8 are in the position corresponding to the normal oil level in the crankcase.
